How Much Crab per Person
Here are two large Dungeness Crabs. For five or six people I usually serve one crab per person and one for the pot.
How much crab to feed a person. How much crab meat from a crab and other yielding factors:
The amount of meat from a crab varies as to the size and specie of the crab. For instance, a Dungeness crab can weigh up to five pounds and usually comes in at between one and one-half and three pounds. The meat-to-shell ratio is about 25%. I recently picked 2.89 pounds of Dungeness crab which resulted in 11 ounces of crab meat or about 24%. I usually buy one large Dungeness per person plus one for the pot when I serve five or six guests.
An Alaskan King crab can weigh up to twenty-five pounds and yield over six pounds of meat. If we consider only the legs; I would bet the yield of meat-to-shell would exceed 50%.
Blue crab yields between ten and fourteen percent meat-to-shell. I once was eating Blue crab on the Chesapeake Bay and had to order French fries because I remained hungry without something other than the crab.
Another statistic of value to people eating Blue crabs is the number of crabs per bushel. Very large crabs (slightly over 6 inches) will number between 60 and 70 crabs per bushel. Medium crabs (about 5 inches) will number between 85 and 100 crabs per bushel. I am told one bushel of Blue crab will feed about ten to twelve people.
Both the Deep Sea Red Crab and the Brown Crab yield about 35% meat to total weight - very high!
I purchased some "Snow Crab Clusters" at Safeway and they yielded 31% meat to shell. I believe these crabs were opilio or opies as they are called in Alaska. chionoecetes opilio
